Electronic apparatus and method for controlling the same

An electronic apparatus comprising:

• communication circuitry configured to communicate with an external terminal;
• and
• a processor configured to drive one of a normal operating system (OS) and a secure OS to perform an operation of the electronic apparatus, the electronic apparatus including both the normal OS and the secure OS;
• wherein the processor of the electronic apparatus is configured to:
• search for at least one external terminal in which a secure OS is installed;
• select a first terminal, from among the searched at least one external terminal, in which the secure OS and the normal OS are installed;
• control the communication circuitry to perform communication between the electronic apparatus and the first terminal;
• search for at least one terminal in which the normal OS is installed, from among at least one external terminal that is capable of being connected to the first terminal;
• select a second terminal, from the searched at least one terminal, in which the normal OS is installed but the secure OS is not installed, wherein the second terminal is capable of being connected to the first terminal;
• and
• control the communication circuitry to perform communication between the electronic apparatus and the selected second terminal in which the normal OS is installed and the secure OS is not installed, through the first terminal in which both the normal OS and the secure OS are installed.

A computer readable non-transitory recording medium having recorded thereon a program for executing a method for controlling an electronic apparatus in which a normal operating system (OS) and a different secure OS are installed, the method comprising:

• searching, by the electronic apparatus which includes the normal OS and the secure OS, for at least one external terminal in which a secure OS is installed;
• selecting, by the electronic apparatus which includes the normal OS and the secure OS, a first terminal, from among the searched at least one external terminal, in which the secure OS and the normal OS are installed;
• performing communication between the electronic apparatus and the first terminal in response to a first terminal being selected from the retrieved at least one external terminal;
• searching, by the electronic apparatus which includes the normal OS and the secure OS, for at least one terminal in which a normal OS is installed, from among at least one external terminal that is capable of being connected to the first terminal;
• selecting, by the electronic apparatus which includes the normal OS and the secure OS, a second terminal, from the searched at least one terminal, in which the normal OS is installed but the secure OS is not installed, wherein the second terminal is capable of being connected to the first terminal;
• and
• performing communication between the electronic apparatus and the selected second terminal in which the normal OS is installed and the secure OS is not installed, through the first terminal in which both the normal OS and the secure OS are installed.
